One D&D doesn't seem to have much regard for the DM's control over information to the players, sometimes part of the fun is not knowing absolutely what a roll means. Giving the player more ways to game the system is just making it less of a roleplaying game, and taking more tools away from the guy who is doing the lion's share of the storytelling.
They also seem to be making everyone a spellcaster. Even a little work on the presentation would make it more palatable (maybe it's just the playtest). I guess every class ability can be treated like a spell, but I've always thought that if your martial characters' abilities are just a spell with different flavor added to hide that fact, it was pretty lame and not really what I want from a fighter-type. That includes things like superiority die, but just giving the ranger Hunters Mark or Conjure Barrage is like having Rogues all get Sense Vitals at level 1.
